PAMS 4.0  - Technical Support


NO EDITIONS of the PAMS software are affected by the critical vulnerability recently discovered in the Apache Log4j software library.
PAMS does NOT include any Log4j software libraries within the PAMS software application installation folder (this is true for all versions of PAMS 1,2,3,4, client & server editions). No edition of the PAMS software has ever used Log4j.

Before contacting us and to resolve your queries faster, please check the most common PAMS support questions and answers below.

Please Note: For customers still operating our older PAMS 3.0 software (released 2010). Most of the support info below will still be relevant (file save paths etc). We do however recommend upgrading to
PAMS 4.0 as soon as possible.

Will PAMS 4.0 work on Microsoft Windows?

PAMS 4.0 has been designed to work on Microsoft Windows. This includes Windows 8/10/11 and Windows Server 2012\2016\2019\2022.

Installing PAMS 4.0

To install PAMS 4.0 software on your PC you will receive a download link in your purchase confirmation e-mail. Click on the download link and wait approx 10 for the file to finish downloading.
Double click on the PAMS 4.0 setup file and the setup procedure will start.
Follow the setup
procedure to install PAMS 4.0. Please Note: You will need to be logged into Windows as an Administrator user to allow you to install the software. If you aren't then Windows will block you from installing any software. Also please allow the entire PAMS 4.0 setup file to download before double clicking to install it.

If you receive the error message "‘could not write value application description to key verify that you have sufficient access to that key" then this is related to you not being
logged into Windows as an Administrator user. To resolve, log into Windows as an Administrator user and then install PAMS 4.0.

Please Note: PAMS 4.0 is developed and licensed to only install and execute on standalone computers running Microsoft WIndows.

Installation File Path information for IT Support 

PAMS 4.0 by default installs in "C:\Program Files\PAMS Assessments Ltd\PAMS 4.0". However you can change this installation path during the setup process.
PAMS 4.0 is designed to work with Windows Local and Domain User Groups. During operation PAMS 4.0 will by default save all created files only into the current logged on user folder. The user can over-ride this and save files anywhere their Windows session permits them to. By default Windows will not allow Users to Read and Write data into User folders other than their own.
All user data is saved by default in the unique Windows path of their "AppData" folder. If you have the AppData folder redirecting to a network server then PAMS will see this and save to this location.
Users can save 7 different file types from PAMS 4.0. For information on the User data file paths see "Locating User Files saved in PAMS 4.0" below.

Privacy and Data Protection

We take data protection and the privacy of our customers very seriously. PAMS 4.0 does not share any data or files saved by the user with anyone. Only the user who has created these files has access to them.

How to Register PAMS 4.0

After installing PAMS 4.0, it has to be registered to activate. Without registration,
saving and printing is disabled.

printing blank worksheets for use in clinical assessments

If you would like to print off blank worksheets from PAMS 4.0, e.g. to be completed by hand in clinical assessments; on the main PAMS 4.0 screen, click the "Worksheet" button and then click "New Worksheet". Complete the "Name", "Assessor" and "Date" fields and click 'Ok'.

A blank worksheet will then be created for you, of which you can print as required.

Problems Running PAMS 4.0

If after having installed and registered you are having difficulties running PAMS, this could be for the following reasons:

1) If you are finding PAMS is freezing a lot and the window becoming un responsive, this could be due to your computer not having enough resources to run PAMS successfully.
he minimum specification to run PAMS is 4GB RAM, 2 GB free disk space, Windows: 7/8/10/Windows Server 2008/R2/2012/2016 and a processor clock speed of 1.5Ghz.

Please note that the above spec is the absolute minimum required to run PAMS. For smooth running of PAMS 4.0, we however recommend the following minimum specification:8GB RAM, 4GB disk space Windows : Windows 8/10 Windows Server 2008/R2/2012/2016 and a processor clock speed of 3Ghz.

2) If you are finding PAMS is freezing a lot and the window becoming un responsive, this could be due to you having too many other software applications running at the same time you are running PAMS.
To avoid this happening, please make sure you close any other software applications which are running, of which you don't need.
This will free up more memory and resources for PAMS to run more smoothly.
If PAMS is still running slowly or not at all we recommend restarting your computer (remember first to save any open files you require saving) and then opening PAMS.


By default in PAMS 4.0 when you save a file this will be in the default folder location under PAMS 4.0 in your APPDATA folder (see "Locating user files saved in PAMS 4.0" below).
However you can change the default location by browsing to any folder on any drive you wish and saving the file. This will then become the default file saving location for that file type. You will need to do this for each PAMS file type.
NOTE: To change the default saving location for PAMS Report files, load PAMS and click the 'Report' button and then the 'Customise Report' button. You can change the Report saving file location in this 'Customise Report' window.

Locating User Files Saved in PAMS 4.0

If you are using PAMS 4.0 and are trying to locate your "I Need Help", "Initial Screening Tool", "Observation", "Worksheet", "Case File", "Parent Questionnaire" or "Report" saved files, the easiest way to find them is to load PAMS 4.0 and click on the menu option "Manage Files". A drop down menu will appear displaying the 7 file types described above. Clicking on each file type will open the "Windows Explorer" window showing the file folder location.

If you prefer to find the files manually then your files will be in one of the default locations below:

Windows 7/8/10:

Most likely here: "C:/Users/[Your Windows UserName]/AppData/Roaming/PAMS 3.0/"


"C:/Users/[Your Windows UserName]/AppData/Local/PAMS 3.0/"

Please note the above file path is often hidden by Windows 7/8/10 so you will need to select "Show All Hidden Files" in your Windows explorer settings.

However if you changed the default folder path and navigated to a different folder to save your file, this can be found by doing a Windows Explorer file search for the following file extensions to reveal all files saved on your computer:

i) Worksheet file - search for ".wst" files
ii) Initial Screening Tool File - search for ".ist" files
iii) I Need Help - search for ".inh" files
iv) Observation files - search for ".obs" files
v) Report files - search for ".doc" files
- search for ".docx" files

vi) Parent Questionnaire files - search for ".doc" files
- search for ".docx" files
vii) Case Files - search for ".csf" files

Important Information regarding Saving Files

Please note that when saving files in PAMS 4.0, users should never save files in the 'System Files' folder. The 'System Files' folder should be used by the PAMS 4.0 application only for generating temporary files for internal processing. All files in the 'System Files' folder are deleted everytime PAMS 4.0 closes. Therefore users should never save any files in this folder. The 'System Files' folder will be in one of the locations below:

Windows 7/8/10:
"C:/Users/[Your Windows UserName]/AppData/Local/PAMS 3.0/System Files"

or "C:/Users/[Your Windows UserName]/AppData/Roaming/PAMS 3.0/System Files"

Please note the above file path is often hidden by Windows 7/8/10 so you will need to select "Show All Hidden Files" in your Windows explorer settings.

Printing Problems

If you are encountering printing problems in PAMS 4.0 then we advise you to check all the points below:

i) Check your printer cable connection is inserted firmly in place at both ends.

ii) Check you have the latest printer driver installed for your particular printer model. If you are unsure of how to do this, ask your IT department for help with this.

iii) Try restarting your printer and also your computer and then printing again.

iv) Try printing to a different printer.

v)  If you are using PAMS 4.0 and have your Windows 'APPDATA' folder redirected to a network location then make sure your network is working correctly. PAMS 4.0 caches temporary files when printing and any issue with your network could cause PAMS printing to fail. Check with your IT department to see if your network is working correctly.

vi) In very rare cases some printers may have problems printing from PAMS. Related symptoms are printouts being scaled either too big or too small.  The cause of this is related to the default printer or printer resolution being changed before printing commences. A quick fix for this is not to modify the printer or printing resolution (from the default printer settings) before clicking the 'Print' button. If you need to print to a different printer or print to a different resolution then make this your default windows printer settings before clicking the 'Print' button.

PAMS 4.0 - "Could not initialize class" on startuP

On opening PAMS 4.0 you may receive the error message: "Could not initialize class at pam.gui.PamsMain.main".

This error message is caused because you do not have a default printer installed on your PC (in Microsoft Windows). To resolve this error please install a default printer to your PC Windows Operating System. After this has been done PAMS 4.0 will open correctly without error.

PAMS 4.0 - Installation error - "This App Can’t Run On Your PC"

On installing PAMS 4.0 on Windows 8/10 you may receive the error "This App Can’t Run On Your PC". This error is caused by Microsoft Windows being over cautious and blocking the PAMS software from installing. The PAMS software is perfectly safe to install on your PC.
There are various actions you can take to override this and install PAMS.

If you disable your Windows "SmartScreen" so PAMS 4.0 will install, we strongly advise reactivating it as soon as PAMS has installed. Windows SmartScreen is important for your PC's security.

PAMS 4.0 - 32 bit and 64 bit editions

PAMS 4.0 when installed on 64-bit PCs can now scale up (available in PAMS 4.092 update) in accordance with 'Windows Display Scaling (250% etc)'. This fixes the issue of PAMS 4.0 appearing very small on high resolution screens and not scaling previously. This new scaling feature in PAMS is not included in the 32 bit edition. To check which PAMS edition you have installed, select 'Help' from the PAMS menu and then click 'About PAMS 4.0'.
